I need help making a bell curve graph and will show us the profit (%) we made over a month. I have all the numbers listed and I'm pretty sure I found the standard deviation. I just don't know how to make the graph.

On the graph I need the bell curve to follow the overall profit %'s values
and the customer 1 profit's data to be on top of it to compare one customers profit with the entire company's profit.
(if that's even possible)

Thanks
